Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a lifting structure of a frameless vehicle door and a vehicle having the same. Background Art

[0002] Car doors are important components of automobiles. They provide access for drivers and passengers, and also serve to isolate the vehicle from the outside environment and mitigate side impacts. Car doors in the prior art typically include door sheet metal, door trim panels fixed to the door sheet metal, door glass fixed between the door sheet metal and the door trim panels in a liftable manner, and glass guide channels that match the door glass. Depending on whether a glass frame is provided on the door sheet metal, car doors can be roughly divided into two types: framed doors and frameless doors. Compared to traditional framed doors, frameless doors have many advantages, such as a stylish appearance, good sound insulation, and a wide field of view. Therefore, frameless doors are becoming increasingly popular in mid- to high-end cars.

[0003] In traditional framed doors, the glass run channel is conveniently fixed to the glass frame, and the door glass can be directly inserted into the groove of the glass run channel during the lifting process, thus achieving an effective guiding and sealing effect. Since frameless doors do not have a glass frame, the glass run channel is usually fixed directly to the body of the vehicle. The door glass directly abuts the glass run channel during the lifting process to achieve the purpose of sealing.

[0004] Figure 1 This is a schematic diagram of the structure of the door glass of a frameless door in the prior art rising and falling along the glass guide groove. Figure 1 As shown, in the prior art, because the lifting direction of door glass 01 always aligns with glass run channel 02 (i.e., "straight up and straight down"), glass run channel 02 constantly rubs against door glass 01 during the lifting process, causing glass run channel 02 to easily deform. Furthermore, during the lifting process, friction is most severe at the lower portion of glass run channel 02, while friction is least severe at the upper portion. This results in inconsistent friction throughout the entire glass run channel 02, which can also cause deformation, thereby reducing its sealing performance and service life.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0006] To address the technical problem of existing frameless door lifting structures easily deforming the glass run channel, the present invention provides a frameless door lifting structure. The lifting structure comprises: a glass run channel having a vertically extending centerline; a door glass having a preset highest position abutting the glass run channel, a preset lowest position disengaged from the glass run channel, and a preset contact position between the preset highest and lowest positions; and a lifter configured to control the door glass to rise and fall straight along a lifting direction between the preset highest and lowest positions, wherein the lifting direction forms a predetermined acute angle with the centerline.

[0007] The lifting structure of a frameless vehicle door according to the present invention includes a glass run channel, a door glass, and a lifter. The glass run channel has a vertically extending centerline to mate with the door glass. The door glass has a preset uppermost position where it abuts the glass run channel, a preset lowermost position where it is disengaged from the glass run channel, and a preset contact position between the preset uppermost and lowermost positions. When the door glass is at the preset uppermost position, the door glass fully abuts the glass run channel (i.e., the contact area is maximized), achieving a good seal. When the door glass is at the preset lowermost position and before moving from the preset lowermost position to the preset contact position, the door glass fully disengages from the glass run channel to avoid excessive contact and friction with the glass run channel. When the door glass is at the preset contact position, the door glass and the glass run channel either begin to contact or begin to disengage. Specifically, when the door glass rises from the preset lowermost position to the preset contact position, the door glass and the glass run channel transition from a disengaged state to an initiated contact state; and when the door glass descends from the preset uppermost position to the preset contact position, the door glass and the glass run channel transition from a fully abutted state to an initiated disengagement state. The lifter is configured to control the door glass to rise and fall straight along a lifting direction between a preset upper and lower positions, automatically adjusting the height of the door glass. The lifting direction forms a predetermined acute angle with the centerline of the glass run channel. Specifically, the door glass rises obliquely toward the glass run channel and descends obliquely away from the glass run channel. This arrangement ensures that during the lifting process, the door glass only contacts and rubs between the preset contact position and the preset upper position, rather than throughout the entire lifting process. This significantly reduces wear on the glass run channel and minimizes the potential for deformation. Furthermore, by delaying the onset of contact during ascent and accelerating the onset of disengagement during descent, friction uniformity across the glass run channel is improved, further reducing the potential for deformation and significantly enhancing the sealing performance and service life of the glass run channel.

[0008] In the preferred technical solution for the aforementioned lifting structure for a frameless vehicle door, the vertical edge of the door glass adjacent to the glass run channel is parallel to the centerline, such that when the door glass is in the predetermined contact position, the vertical edge contacts the glass run channel. This arrangement ensures that, when the door glass is in the predetermined contact position, the entire vertical edge of the door glass adjacent to the glass run channel contacts the glass run channel. In other words, initial contact between the door glass and the glass run channel occurs at a linear level, rather than at a point, thereby reducing localized wear on the glass run channel.

[0009] In the preferred technical solution of the lifting structure for the frameless vehicle door, when the vehicle door glass is at the predetermined highest position, the vertical edge coincides with the center line. This arrangement allows the vertical edge to be located approximately in the middle of the glass run channel when the vehicle door glass is at the predetermined highest position, thereby achieving a good sealing effect.

[0010] In a preferred embodiment of the aforementioned lifting structure for a frameless vehicle door, the glass run channel includes a first glass run channel and a second glass run channel, respectively located on either side of the door glass. The first glass run channel has a first centerline, and the second glass run channel has a second centerline. The lifting direction forms a first predetermined acute angle and a second predetermined acute angle with the first and second centerlines, respectively. The predetermined angle formed by the first and second centerlines is equal to the sum of the first and second predetermined acute angles. This arrangement reduces friction on the first and second glass run channels during lifting and lowering of the door glass, thereby improving the sealing performance and service life of the first and second glass run channels.

[0011] In the preferred technical solution of the aforementioned lifting structure for a frameless vehicle door, the first predetermined acute angle is equal to the second predetermined acute angle. This arrangement ensures that the door glass exerts substantially equal friction on the first and second glass run channels when raised or lowered along the lifting direction, thereby improving the uniformity of wear on the first and second glass run channels.

[0012] In a preferred embodiment of the aforementioned lifting structure for a frameless vehicle door, the lifting structure further includes an outer water cut and an inner water cut opposing each other, with the door glass positioned between the outer and inner water cuts. This arrangement allows the door glass to contact the outer and inner water cuts during the lifting process, thereby removing impurities such as dust and water droplets from the inner and outer surfaces of the door glass.

[0013] In the preferred technical solution of the lifting structure of the frameless vehicle door, the inner water cut has an inner water cut angle, and a receiving groove for receiving the vertical edge is formed on the inner water cut angle. This arrangement can enhance the guiding and restraining effect on the vehicle door glass.

[0014] In the preferred technical solution of the aforementioned lifting structure for a frameless vehicle door, when the vehicle door glass is at the predetermined highest position, the vehicle door glass is inserted into the receiving groove, and the vertical edge abuts against the receiving groove. When the vehicle door glass is at the predetermined highest position, the vertical edge of the vehicle door glass is configured to abut against the receiving groove, thereby achieving a good sealing effect between the vehicle door glass and the inner water shear angle.

[0015] In the preferred technical solution for the aforementioned frameless door lifting structure, the predetermined acute angle is in the range of 1°-2°. This arrangement ensures that the predetermined acute angle falls within a moderate range, preventing excessive angles from causing the door glass to occupy excessive space during lifting, while also preventing excessive angles from increasing the travel of friction between the door glass and the glass run channel.

[0016] To address the technical problem of existing frameless door lifting structures easily causing deformation of the glass run channel, the present invention provides a vehicle. The vehicle includes any of the above-described frameless door lifting structures. By employing any of the above-described frameless door lifting structures, the vehicle of the present invention effectively reduces the likelihood of deformation of the glass run channel, improves the sealing performance and service life of the glass run channel, and thus enhances the user experience.

[0034] Next, combine Figure 2-Figure 8 An embodiment of the lifting structure 30 for a frameless vehicle door 20 according to the present invention will be described in detail.

[0035] Figure 3 Schematic diagram of the structure of the embodiment of the lifting structure of the frameless door of the present invention. Figure 3 As shown, in one or more embodiments, the lifting structure 30 of the present invention includes components such as a glass run channel 31 , a door glass 32 , and a lifter 33 .

[0036] Continue to see Figure 2 and Figure 3The glass run channel 31 is fixed to the vehicle body 11. In one or more embodiments, the glass run channel 31 includes a first glass run channel 31a, a second glass run channel 31b, and a top glass run channel 31c located between the first and second glass run channels 31a, 31b, forming a generally U-shaped configuration. The first glass run channel 31a extends generally vertically and is fixed to the C-pillar 112. The second glass run channel 31b also extends generally vertically and is fixed to the B-pillar 111. The top glass run channel 31c is located above the first and second glass run channels 31a, 31b, and extends generally horizontally. The top glass run channel 31c is fixed between the B-pillar 111 and the C-pillar 112. Methods for fixing the glass run channel 31 to the vehicle body 11 include, but are not limited to, bonding, snapping, and the like. Alternatively, the second glass run channel 31b and the top glass run channel 31c may be configured as a single, curved shape.

[0037] Figure 4 1 is a cross-sectional schematic diagram of an embodiment of the door glass and glass run channel in the lifting structure of the frameless door of the present invention. Figure 4 As shown, in one or more embodiments, the glass run channel 31 includes a channel body 311. The channel body 311 can be made of a suitable rubber material (e.g., EPDM) to provide excellent elasticity, resistance to compression deformation, aging resistance, ozone resistance, and chemical resistance. Multiple spaced-apart lips 312 are provided on the side of the channel body 311 facing the door glass 32 to enhance the seal between the door glass 32 and the glass run channel 31. The number and specific structure of the lips 312 can be adjusted based on actual needs.

[0038] Continue to see Figure 3 In one or more embodiments, the door glass 32 includes a door glass body 321. The door glass body 321 can be made of double-layer laminated tempered glass, so that it has good mechanical properties and explosion-proof properties. That is, the door glass body 321 is composed of two pieces of tempered glass, with one or more layers of polymer film sandwiched in the middle. The polymer film can be PVB, SGP, EVA, PU or other suitable materials. Alternatively, the door glass body 321 can also adopt other suitable structures. The door glass 321 has a vertical edge 322 extending roughly in the vertical direction. In one or more embodiments, the vertical edge 322 includes a first vertical edge 322a and a second vertical edge 322b opposite to each other. Based on Figure 3In the illustrated orientation, the first vertical edge 322a is on the left, while the second vertical edge 322b is on the right. The door glass body 321 also has a top edge 323 located at its upper portion and extending generally horizontally. Alternatively, the second vertical edge 322b and the top edge 323 may be formed into a single, curved structure. Two spaced-apart connection holes (not shown) are provided at the lower portion of the door glass 321 to securely connect it to the lifter 33.

[0039] Continue to see Figure 3 In one or more embodiments, the lifter 33 is an arm-type glass lifter. The arm-type glass lifter can be a single-arm glass lifter or a double-arm glass lifter, etc. Alternatively, the lifter 33 can also be a flexible glass lifter. The flexible glass lifter can be a pulley-type glass lifter, a belt-type glass lifter, or a flexible shaft-type glass lifter, etc. The lifter 33 is fixed to the door sheet metal 21 and is arranged in a cavity enclosed by the door sheet metal 21 and the door trim. The lifter 33 is configured to be controlled to open and close by a button switch (not shown in the figure) on the vehicle 1, thereby driving the door glass 32 to rise and fall.

[0040] Figure 5 1 is a schematic diagram of the structure of the first embodiment of the door glass in the lifting structure of the frameless door of the present invention in different lifting positions. Figure 5 As shown, in one or more embodiments, the glass run channel 31 has a centerline L1 extending generally vertically. In other words, the "glass run channel 31" referred to herein may be the first glass run channel 31a or the second glass run channel 31b, but does not include the top glass run channel 31c. The door glass 32 has a predetermined lowest position I, where it is disengaged from the glass run channel 31; a predetermined highest position III, where it abuts against the glass run channel 31; and a predetermined contact position II, located between the predetermined lowest position I and the predetermined highest position III. Under the control of the lifter 33, the door glass 32 is raised and lowered along a lifting direction L2 between the predetermined lowest position I and the predetermined highest position III. The lifting direction L2 and the centerline L1 form a predetermined acute angle α. In one or more embodiments, the predetermined acute angle α is in the range of 1°-2°, providing a moderate angle. Alternatively, the predetermined acute angle α may be set to another suitable acute angle.

[0041] Continue to see Figure 5In one or more embodiments, the vertical edge 322 of the door glass 32 on the side closest to the glass run channel 31 is extended by a line L3, and this extension line L3 is parallel to the centerline L1 of the glass run channel 31. This arrangement ensures that when the door glass 32 is in the predetermined contact position II, the entire vertical edge 322 is in contact with the glass run channel 31. In other words, the door glass 32 and the glass run channel 31 are in line contact, rather than point contact, thereby reducing localized wear on the glass run channel 31 caused by the door glass 32. Furthermore, the arrangement of the vertical edge 322 parallel to the centerline L1 of the glass run channel 31 delays contact between the door glass 32 and the glass run channel 31, further reducing wear on the glass run channel 31 caused by the door glass 32. Alternatively, the extension line L3 of the vertical edge 322 can be arranged at a certain angle, such as 0.5° or 0.8°, relative to the centerline L1 of the glass run channel 31.

[0042] Continue to see Figure 5 In one or more embodiments, when the door glass 32 is at the predetermined uppermost position III, the vertical edge 322 coincides with the centerline L1 of the glass run channel 31. That is, the vertical edge 322 is located approximately in the middle of the glass run channel 31 to achieve a good sealing effect. Alternatively, the vertical edge 322 may be located at another suitable position to the left or right of the centerline L1 of the glass run channel 31.

[0043] When the door glass 32 rises from the preset lowest position I to the preset contact position II, the door glass 32 and the glass run channel 31 do not come into contact, and no friction occurs between them. When the door glass 32 rises from the preset contact position II to the preset highest position III, the door glass 32 and the glass run channel 31 abut against each other, generating friction. Accordingly, when the door glass 32 descends from the preset highest position III to the preset contact position II, friction occurs between the door glass 32 and the glass run channel 31. However, when the door glass 32 descends from the preset contact position II to the preset lowest position I, the door glass 32 and the glass run channel 31 separate. Therefore, throughout the entire raising and lowering process, friction between the door glass 32 and the glass run channel 31 occurs only between the preset contact position II and the preset highest position III, significantly reducing wear on the glass run channel 31 and the potential for deformation of the glass run channel 31. In addition, compared with the "straight up and straight down" lifting structure, the door glass 32 is set to contact the glass guide groove 31 from the preset contact position II (or, to separate from the glass guide groove 31 from the preset contact position II), which can effectively avoid severe wear on the lower part of the glass guide groove 31 and slight wear on the upper part, thereby improving the uniformity of the wear degree of various parts of the glass guide groove 31, thereby further reducing the possibility of deformation of the glass guide groove 31.

[0044] It should be noted that when the door glass 32 is at the preset highest position III, the contact area between the door glass 32 and the glass run channel 31 is Figure 5 The gray area shown. This contact area can be compared with the contact area between the door glass 01 of the prior art and the glass run channel 02 of the prior art (see Figure 1 In other words, the lifting structure 20 of the present invention can achieve substantially the same sealing effect as that of the prior art.

[0045] Figure 6 1 is a schematic diagram of the structure of the second embodiment of the door glass in the lifting structure of the frameless door of the present invention in different lifting positions. Figure 6 As shown, in one or more embodiments, the door glass 32 has a first vertical edge 322a and a second vertical edge 322b opposite to each other, and the first glass run channel 31a and the second glass run channel 31b are respectively located on the left and right sides of the door glass 32. The first glass run channel 31a matches the first vertical edge 322a, and the second glass run channel 31b matches the second vertical edge 322b. The first glass run channel 31a has a first center line L11 extending substantially vertically, and the second glass run channel 31b has a second center line L12 extending substantially vertically. The first center line L11 and the second center line L12 are clamped to form a predetermined angle β. The door glass 32 has a preset lowest position I separated from the first glass run channel 31a and the second glass run channel 31b, a preset highest position III resting on the first glass run channel 31a and the second glass run channel 31b, and a preset contact position II located between the preset lowest position I and the preset highest position III. See Figure 6In one or more embodiments, when the door glass 32 is in the preset contact position II, the first vertical edge 322a of the door glass 32 begins to contact the first glass run channel 31a. At this point, the second vertical edge 322b is still disengaged from the second glass run channel 31b. That is, the first vertical edge 322a contacts the first glass run channel 31a first, followed by the second vertical edge 322b. Alternatively, the door glass 32 may be configured such that the second vertical edge 322b contacts the second glass run channel 31b first, or the first and second vertical edges 322a, 322b contact the corresponding first and second glass run channels 31a, 31b simultaneously. Under the control of the lifter 33, the door glass 32 is raised and lowered along the lifting direction L2 between the preset lowest position I and the preset highest position III. The lifting direction L2 and the first centerline L11 form a first predetermined acute angle α1, and the lifting direction L2 and the second centerline L12 form a second predetermined acute angle α2. Specifically, the predetermined angle β formed between the first centerline L11 and the second centerline L12 is equal to the sum of the first predetermined acute angle α1 and the second predetermined acute angle α2. In one or more embodiments, the first predetermined acute angle α1 ranges from 1° to 2°, and the second predetermined acute angle α2 also ranges from 1° to 2°. In one or more embodiments, the first predetermined acute angle α1 is equal to the second predetermined acute angle α2, so that when the door glass 32 is raised and lowered along the lifting direction L2, it exerts substantially equal friction on the first and second glass run channels 31a, 31b, thereby improving the uniformity of wear on the first and second glass run channels 31a, 31b. It should be noted that the portions not mentioned in the second embodiment may be configured identically to those in the first embodiment and are not further described here.

[0046] like Figure 3 As shown, in one or more embodiments, the lifting structure 30 for a frameless vehicle door 20 of the present invention further includes an outer sheath 34 and an inner sheath 35 that match each other. The outer sheath 34 and the inner sheath 35 extend generally in the front-to-back direction of the frameless vehicle door 20. Both the outer sheath 34 and the inner sheath 35 can be made of a suitable resin material (e.g., PVC, TPV, EPDM, etc.) and fixed to a frame (e.g., aluminum strip) through an extrusion process. The outer sheath 34 and the inner sheath 35 can be fixed to a suitable location on the frameless vehicle door 20, such as the door sheet metal 21 or the door trim, by snapping, screwing, or other suitable fixing methods. The outer sheath 34 and the inner sheath 35 are located on the outer and inner sides of the door glass 32, respectively. That is, the door glass 32 is fixed between the outer sheath 34 and the inner sheath 35 so that it can be lifted and lowered. Through the above arrangement, the door glass 32 rubs against the outer water cut 34 and the inner water cut 35 during the lifting process, thereby removing impurities such as dust and moisture on the surface of the door glass 32 .

[0047] Figure 7This is a schematic diagram of the structure of an embodiment of the door glass and inner water cut angle in the lifting structure of the frameless door of the present invention. Figure 3 and Figure 7 As shown, in one or more embodiments, an inner cutout 35 is further provided with an inner cutout angle 36. The inner cutout angle 36 is disposed at the end of the inner cutout 35 and positioned below the glass run channel 31. The inner cutout angle 36 comprises an angle body 361. This angle body 361 can be made of a suitable resin material (e.g., PVC, TPV, EPDM, etc.). The angle body 361 is provided with a receiving groove 362 for receiving the door glass 32. Specifically, the vertical edge 323 of the door glass 32 can be inserted into the receiving groove 362, providing good guidance and positioning for the door glass 32 during the raising and lowering process.

[0048] Figure 8 This is a schematic diagram of the structure of the lifting structure of the frameless door of the present invention, in which the door glass and the inner water cut angle are at different lifting positions. Figure 8 As shown, in one or more embodiments, when the door glass 32 is in the preset lowest position I, it is inserted into the receiving groove 362 of the corner body 361, with a gap W between the vertical edge 323 and the bottom of the receiving groove 362. The door glass 32 moves obliquely toward the glass run channel 31 along the lifting direction L2. When the door glass 32 is in the preset highest position III, it moves toward the corner body 361, and the vertical edge 323 abuts the bottom of the receiving groove 362. Accordingly, as the door glass 32 descends from the preset highest position III toward the preset lowest position I, the vertical edge 323 moves away from the corner body 361 and disengages from the bottom of the receiving groove 362. Therefore, when the door glass 32 is in the preset highest position III, the vertical edge 323 completely fills the receiving groove 362, improving the sealing effect between the door glass 32 and the inner water-cut corner 36. In addition, when the door glass 32 is in a non-preset highest position III, the door glass 32 moves obliquely in a direction away from the corner body 361, so that the vertical edge 323 is separated from the bottom of the receiving groove 362 by a certain distance, effectively preventing the vertical edge 323 from rubbing against the corner body 361 during the lifting process, thereby improving the service life of the inner water cutting corner 36.

[0049] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
